36 MODELS · 9 NOMINAL OPENINGS
Standard sizes of copper–aluminium heat exchangers Choose a function and nominal opening, then compare the frame, casing and connections in the model card. These are sizes of the illustrated series, not a universal interchangeability standard.
The coils in this catalogue have copper tubes and aluminium fins. “Aluminium” here describes the fins; it does not identify an all-aluminium coil.
Water cooling coils 9 models Refrigerant cooling coils 9 models Liquid heating coils 18 variants Compare the nine nominal sizes Models and dimensions Selection requirements Questions about standard coil sizes Compare the nine nominal sizes Each cell links to the exact model card. Read dimensions as frame width × height / casing depth, in mm; connections may project beyond these dimensions.
On a narrow screen, scroll the table horizontally.
“?” marks a dimension with conflicting source values. Open the model card to see both values.
Heater variants 2 and 3. Do not transfer a rating between variants. Matching performance-table rows are available for variant 2; variant 3 has drawings, but lacks its own table. A separate historical product description is identified in the relevant card.

Recovered product description The previous site describes a 1000 × 500 variant-3 heater as a glycol unit and states 6900 m³/h, 119 kW and 82 Pa. The operating conditions and mixture are not specified, so these are historical figures, not a current selection.
Choose the function, fluid and fit A size is one part of selection. These three checks link the catalogue to the right application and replacement requirements.
1. Heating or cooling Choose the heat-transfer task first. A refrigerant cooling coil and an air-cooled condenser perform different duties and need separate selection.
2. Water, glycol or refrigerant State the fluid, temperatures and flow. For glycol, add its type and concentration; for a refrigerant, its designation and evaporating or condensing conditions.
3. Installation and connections Compare the opening, frame, depth, mounting holes and pipe positions. Define connection handedness relative to airflow; a perspective render cannot establish it.
Water, glycol or refrigerant? The fluid is a selection input, not a size. Specify water or the type and concentration of glycol; for a refrigerant coil, specify the refrigerant and operating conditions. A matching duct opening alone does not establish a suitable replacement.
Dimensions are taken from archive drawings and, where available, matching catalogue tables. Final supply requires an agreed drawing; the illustrations are not manufacturing documents. Frame and casing dimensions exclude some projecting parts. Confirm the full envelope, mounting holes and connections against your installation.
Questions about standard coil sizes Does a matching nominal size guarantee a replacement? No. Check the complete envelope, mounting, connections, airflow direction and required operating performance. The size label identifies the nominal opening, not every installation interface.
Do variants 2 and 3 have the same performance? Do not transfer a rating between variants. Matching performance-table rows are available for variant 2; variant 3 has drawings, but lacks its own table. A separate historical product description is identified in the relevant card.
What if none of the nine openings fits? Use the made-to-size or replacement route. Provide a drawing or measured dimensions and the operating duty; the series catalogue is not a limit on possible project specifications.
